PFAS are present in freshwater fish in the Danube River, posing concerns about aquatic ecosystem contamination and adverse effects on human health. These substances also referred to as “forever chemicals” have the potential to accumulate in the food chain and provoke several health issues, including hormonal imbalance and cancer. In this work, the QuEChERS extraction and clean-up method combined with UHPLC-HRMS (Ultra-High-Performance Liquid Chromatography – High-Resolution Mass Spectrometry) was applied for the determination of 18 PFAS in muscle tissue of freshwater fish (European wels catfish – Silurus glanis). The method was validated in terms of Specificity, Linearity, Precision (% RSD), Recovery, and Accuracy (mean spike recovery, %) at two levels of concentration: 0.1 and 5 ng. Additionally, the study assessed the impact of matrix effects on PFAS detection in fish tissue.
